program to accept a character in lowercase and convert it into uppercase

 /* write  a program to accept a character in lowercase and convert it into uppercase using  library function*/

#include<stdio.h>

#include<conio.h>

void main()

{            char ch;

              clrscr();

              printf(" \n Enter a character in lowercase :--");

              scanf("%c",&ch);

              ch=toupper(ch);

              printf(" \n  uppercase character = %c ",ch);

             getch();

}

/* output:--

                 Enter a character in lowercase :-- b

                 uppercase character  = B

*/

Algorithm of program

step 1: start

step 2: Declare ch

step 3: Accept character in lowercase

step 4: IS   ch=toupper(ch)

step 5:Display   uppercase character 

step 6:stop

Conditional and Ternary operator ( ?, : )

 Conditional and Ternary operator ( ?, : )

Conditional and Ternary operator is used to check the condition at that place of it by using this operator we can  minimize the length of the program because true part and false part of condition is written in a single line.

Syntax 

(condition )? true part : false part 

Examples:--

/*Program to find the largest no among two number using conditional and ternary operator  */

#include<stdio.h>

#include<conio.h>

main()

{        int a,b;

          clrscr();

          printf(" \n Enter the value for a and b = \n");

          scanf("%d%d",&a,&b);

          (a>b)?printf("%d is largest ",a) : printf("%d is largest ",b);

         getch();

}

/*    Output:--

                    Enter the value for a and b =20

                                                                  10

                    20 is largest

syntax of c programming language

C language is developed by Dennis Ritchie.

Points to be remember while writing c program

1) every programming instruction must be returned within a main block.

2)All the instructions must be returned in a lowercase, because she is a case sensitive language it knows the difference between lowercase and uppercase.

3) every statement must be ended with a semicolon (;).

4)we May write constant variable or any user-defined thing in capital.

Steps to save ,compile and execute the program

1) save: File->save (F2) i.e first.c

2) compile and execute:Ctrol+F9

Note: if getch () is not there, then we can see the output screen using alt+F5, else directly we can see the output.

Example:

Syntax

Main ()

{           Clrscr();

             Printf("My first program in c.");

             getch ();

}

    Where

            Clrscr (): used to clear the screen.

            Printf ():  to display the text o value of variable on the                                                                     screen.

            getch ():  is used to hold output screen.                                    

Escape Sequences: is used to move the cursor on the particular position

'\n'(newline)           : is used to jump the cursor on the next line.

'\t'(tab)                   : to Move Cursor 5 characters along.

'\r'(carriage return):to move the cursor on the first character of the                                     current line.

'\b'(backspace)       : to jump the cursor one character left.
